Linux Distros Unpatched Vulnerability : CVE-2025-71143

critical Nessus Plugin ID 284695

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- clk: samsung: exynos-clkout: Assign .num before accessing .hws Commit f316cdff8d67 (clk: Annotate struct clk_hw_onecell_data with __counted_by) annotated the hws member of 'struct clk_hw_onecell_data' with
__counted_by, which informs the bounds sanitizer (UBSAN_BOUNDS) about the number of elements in .hws[], so that it can warn when .hws[] is accessed out of bounds. As noted in that change, the __counted_by member must be initialized with the number of elements before the first array access happens, otherwise there will be a warning from each access prior to the initialization because the number of elements is zero.
This occurs in exynos_clkout_probe() due to .num being assigned after .hws[] has been accessed: UBSAN:
array-index-out-of-bounds in drivers/clk/samsung/clk-exynos-clkout.c:178:18 index 0 is out of range for type 'clk_hw *[*]' Move the .num initialization to before the first access of .hws[], clearing up the warning. (CVE-2025-71143)

Note that Nessus relies on the presence of the package as reported by the vendor.
